HEDDLE CONSTRUCTION FOR LOOIVIS.

Application filed March 19, 1923. Serial No. 626,015.

To all whom it may concern:

Be it known that I, lviicemni. S. Sonoxa, a citizen of the United States, residing at Atlanta, in the county of Fulton and St-ate of Georgia, nave invented'new and useful Imzrovements in Heddle Construction for Looms, of which the following is a specification.

This invention in its broadest aspect rebut in the present instance is directed more especially to the type of loom adapted for weaving wicker ware, such as bodies for baby carriages and the like furniture, etc. 7

This invention comprehends harness construction for looms, but with particular reference to the heddles comprised by the harness. -Also, the type of machine comthis invention relates to looms employing a plurality of harness frames designed to operate so that while some of the frames are up others will be down, and vice versa, and susceptible of varying the numas desired.

It has been prevalent to construct the harness or heddle frame so that the heddles carried by the frame move as a unit therewith. And an important object of this invention is to design heddle construction with certain of the heddles independently movable with respect to the frame.

Another object of this invention is to design independently operable heddles adapted to cooperate with and be carried by a selected heddle frame and capable of disengagement therefrom and attachment to another heddle frame to change the warp and vary the shed, as desired.

A principal object of this invention is to provide independently operable heddles for attachment to different heddle frames so that certain warp threads may be raised and depressed out of their normal alternate order, thereby imparting to the fabric, during the process of weaving, a predetermined design.

Vith these and other objects; in view, which will become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which like characters of references indicate like parts throughout the several figures, of which:

Figure 1 is a longitudinally vertical sectional view .of a loom'showing independently movable heddles in operable position. Figure 2 IS a cross sectional view of Fig- 'ure 1, and

rigure 3 1s a detail perspective view of the attachable heddle. I

In the illustrated embodiment characterizmg'this invention there is shown a frame 1 embodying horizontal members 2 and vertical members 3 positioned intermediate the ends of the frame 1 and extending substantially equi-distant above and below the said members 2, for a purpose which will hereinafter more fully appear.

At one xtremity of the frame, the members 3 extend above the horizontal members 2, and are adapted to carry a frame member 4. On the upper extremities of the vertical frame members 3 are suitably journalled the pulleys 5,'an d on the lower extremities are similarly journalled corresponding pulleys 6. Cables 7 are adapted to pass around the pulleys 5 and 6 and have each end secured to the heddle frame 8, as at 9, so as to suspend the heddle frame between the two extremities of the frame structure 3, to permit the said heddle frame or frames to be movable in a vertical plane. It is to be understood of course, that there may be a variationin the number of heddle frame employed, according to the type of loom required. In looms of the character herein specified 1t is prevalent to attach the heddles to the heddle frame, so that the heddles and frame move as a unit, but as such construction only permits of an unvaried weave, I have designed an independently operable heddle l0, normally positioned between two different heddle frames, with its upper extremity terminating in oppositely extending hook portions 11 and 11 adaptedto grippingly engage and be disengaged from certain of the heddle frames, as desired, and when so atv tached to move as a unit with said frame for the purpose of causing the warp thread carried by said heddle to be raised or depressed out of its normal order to change the weave and impart a'predetermined design to the fabric. At the extremity of the loom opposite the warp beam are mounted the batten rollers 1212, and intermediate these rollers and the vertical frame member 3 is positioned the vertical guide or. reed frame 13.

By the employment of the heddle structure forming the subject matter of this invention, the operator is enabled by the employment of a greater or less number of independently operable heddles, the number depending upon the particular design de sired, to so change the normal movement of the Warp threads carried by the independent heddles by manually shifting them from one heddle frame to another that is, by disengaging one of the hook portions from its heddle frame and engaging another heddle frame with the other opposite hook portion, Which procedure is applicable to each of the similar heddles, so as to vary their alternate movement to impart to the fabric or material being Woven, the desired design. Of course, it is obvious by the employment of av diil'eroi'it number of these heddles, any number of Warp threads can be varied from their normal alternate order as desired, de pending upon the exigencies of the situation.

As far as I am aware, it has not been possible by the type of looms now in use to Weave a predetermined design in Wicker- Ware, and in order to accomplish that result and to overcome the more or less slow and tedious operation heretofore no my in this class of Weaving, I have designed the novel attachment for looms forming the subject matter of this invention.

In practice, I have found that the form of my invention illustrated in the accompanying drawings and referred to in the above description, as the preferred embodiment, is the most efficient and practical; yet realizing the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize that various minor changes in details of construction, proportion and arrangement of parts, may be resorted to Within the scope of the appended claim Without departing from or sacrificing any of the principles of this invention.

Having thus described my invention, and Without enumerating variations and equivalents, What I desire protected by Letters Patent is as set forth in the following claim:

In a loom, the combination with heddle frames embodying a plurality of heddles, certain of said heddles having substantially T-shaped means adjacent their upper ends projecting from opposite sides, the means on one side of the heddle adapted for detachable gripping engagement With one heddle frame and the means on the opposite side adaptable for similar engagement with another heddle frame, handle means also provided at the upper ends of said heddles for expeditiously transferring each of the detachable heddles from one heddle frame to another to vary the normal alternate order of the Warp threads. 7
